Orthopter-type wind turbine is a vertical axis wind turbine of which each blade rotates on their own axis meanwhile all of blades rotate on its main axis. The present paper describes the power coefficients of the orthopter-type wind turbine in uniform and shear flows. Three turbulence models, i.e. RNG k-ε, Realizable k-ε and SST k-ω, were investigated in 2-dimensional numerical simulation. The aim of this research is to identify the most reliable and effective turbulence model to simulate the performance of orthopter-type wind turbine. The result of the SST k-ω turbulence model has the closest value to the experimental data.
